Sintered zinc sulfide (ZnS) infrared lens

Maintains optical properties up to around 250℃! Infrared lens with no resource savings.

Our company offers "sintered zinc sulfide (ZnS) infrared lenses," which have a smaller temperature dependence of refractive index compared to conventional materials and can maintain optical properties up to approximately 250°C. Commercial ZnS powder (with particle sizes of a few micrometers) is crushed to particle sizes of several hundred micrometers, and impurities are removed through heat treatment. Subsequently, our product, shaped by discharge plasma sintering into a near-net shape, can withstand harsh environments with rain erosion and temperature fluctuations, making it suitable for outdoor use. 【Features】 ■ Final lens processing possible with minimal removal in the finishing process ■ Transmits a wide range of infrared wavelengths from 0.35 to 15 μm ■ Usable even in areas with significant temperature changes ■ Resource-saving ■ High durability *For more details, please download the PDF or feel free to contact us.
